Failing to file Form 3520 for a Tax-Free Savings Account (TFSA) can trigger a penalty equal to 35% of the account's value — in a single year. A Canadian TFSA worth $40,000 Canadian (roughly $29,000 US) could generate a $10,000 IRS penalty just for a missed reporting form, even if no US tax was owed on the account. Most Americans in Canada have no idea this obligation exists, because Canadian financial institutions have no duty to inform them.

RRSP and TFSA accounts are the two pillars of the Canadian registered savings system. For Canadian citizens and residents without US tax obligations, they work as advertised. For Americans living in Canada — or any US person holding these accounts — both accounts come with hidden IRS reporting layers that most Canadian advisors do not know to flag. Here is what each account means for your US tax return, what you must file, and where the penalties hide.

How the IRS Treats Your RRSP

An RRSP (Registered Retirement Savings Plan) is Canada's equivalent of a traditional IRA — but the IRS does not automatically recognize it as one. Without the treaty election, the IRS taxes RRSP growth every year as ordinary income, just like an unregistered investment account. The Canadian tax exemption on RRSP growth means nothing on your US return unless you specifically invoke treaty protection.

The good news: the US-Canada tax treaty provides this protection. Article XVIII(7) of the US-Canada Income Tax Treaty allows you to elect to defer US tax on undistributed RRSP income until you take a distribution — effectively treating it like a US IRA for deferral purposes. Before 2014, this required a separate form (Form 8891). The IRS eliminated Form 8891 and now allows you to claim this deferral by attaching a written statement to your Form 1040 each year, indicating you are exercising treaty benefits under Article XVIII(7).

The Annual Treaty Statement

Without the treaty statement attached to your return, your RRSP is not deferred. You owe US tax on every dollar of interest, dividends, and capital gains earned inside the RRSP each year, as if the account were a taxable brokerage account. Many Americans in Canada make this mistake in their first year, then retroactively fix it through amended returns or the IRS Streamlined Procedures.

To claim deferral, include a statement with your 1040 that identifies the account, states the fair market value on December 31, notes the income earned during the year, and invokes the deferral election under the Canada treaty. The Form 8833 instructions at IRS.gov describe how to disclose treaty-based return positions. Keep a copy of the RRSP statement from your Canadian institution showing year-end value and income earned inside the plan.

RRSP Withdrawals and US Tax

When you withdraw from an RRSP, Canada withholds tax at the source — typically 25% for non-residents or 15% under the treaty for periodic pension payments. That withheld Canadian tax generates a foreign tax credit on your US return under Form 1116, which can offset the US tax owed on the withdrawal. In many cases, the treaty withholding rate and the US credit mean you pay little additional US tax on RRSP withdrawals — but you must still report the income and claim the credit correctly.

Note that RRSP withdrawals are ordinary income for US purposes, not eligible for long-term capital gains rates, even if the underlying RRSP investments were held for years and grew through capital gains inside the plan.

The TFSA Problem: Foreign Trust Treatment

A TFSA (Tax-Free Savings Account) is entirely tax-free inside Canada — but the IRS does not recognize it and has no equivalent concept. The IRS has historically treated TFSAs as foreign grantor trusts because they are registered accounts with legal arrangements between the account holder and a Canadian institution. If a TFSA is a foreign grantor trust, it triggers two separate filing obligations: Form 3520 and Form 3520-A.

Form 3520: Annual Report for Foreign Trust Transactions

Form 3520 (Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts) must be filed by US persons who are owners of foreign grantor trusts. If your TFSA is classified as a foreign grantor trust, you must file Form 3520 each year reporting the account as a trust you own. The penalty for failure to file is the greater of $10,000 or 35% of the value of the property transferred to or distributed from the trust — per year.

Form 3520-A is the annual information return that the trustee of the foreign trust is supposed to file. Because Canadian TFSA administrators are not US persons, they have no obligation to file Form 3520-A. This means the responsibility falls back on you — the US beneficial owner — to file a substitute Form 3520-A on their behalf. Most US tax preparers unfamiliar with Canadian accounts miss this entirely.

The IRS Position on TFSAs

The IRS has never issued formal published guidance specifically classifying TFSAs as foreign trusts. The position is based on general foreign trust rules under IRC §671-679 applied to the TFSA structure. In practice, many US tax professionals advise filing Form 3520 out of caution; others believe TFSAs may not meet the technical definition of a "trust" under US law and advise against it. The Canadian government has repeatedly asked the IRS to clarify its position and provide treaty relief for TFSAs — without success as of early 2026.

In the meantime, the practical reality is that TFSAs are a compliance landmine for Americans in Canada. The highest-risk approach is to hold a growing TFSA for years without filing Form 3520 and then face a substantial penalty later. The lowest-risk approach is to either avoid TFSAs entirely or keep balances minimal and file Form 3520 each year.

FBAR and FATCA: What You Must Report

Both RRSP and TFSA accounts must be reported on the FBAR (FinCEN Form 114) if the aggregate maximum value of all your foreign financial accounts exceeded $10,000 at any point during the calendar year. This threshold applies to the combined total of all foreign accounts — not each account separately. Many Americans in Canada with even modest savings will exceed it.

The FBAR is filed with FinCEN at fincen.gov, not with the IRS, and is due April 15 with an automatic extension to October 15 if needed. Penalties for willful failure to file can reach $100,000 or 50% of account value per year — one of the harshest civil penalties in the US tax code.

Account	FBAR Required?	Form 8938 Required?	US Tax Deferral Available?
RRSP	Yes (if over $10K threshold)	Yes (if over threshold)	Yes — via treaty election (annual statement)
RRIF (converted RRSP)	Yes	Yes	Yes — same Article XVIII election
TFSA	Yes	Yes	No — growth taxable annually in the US
RESP (Education)	Yes	Yes	No — taxable annually; government grants may trigger Form 3520

Form 8938 (Statement of Specified Foreign Financial Assets) is separate from the FBAR and is filed with your Form 1040. Thresholds are higher: $50,000 for single filers living in the US, or $200,000 for single filers living abroad, at any point in the year. Both RRSP and TFSA qualify as specified foreign financial assets for Form 8938 purposes.

What About RESP Accounts?

A Registered Education Savings Plan (RESP) creates similar US complications. The Canadian government contributes matching grants to RESP accounts (the Canada Education Savings Grant, up to $500/year per child). For US tax purposes, the RESP itself may be a foreign trust, and the government grant is taxable income in the year received — it is not sheltered by any treaty provision.

For American families in Canada with children, the RESP creates an annual US income inclusion equal to the government grant received, plus potentially a Form 3520 filing obligation. Some cross-border tax professionals advise against holding RESPs for US citizen children for this reason; others argue the tax cost of the inclusion is modest relative to the grant benefit.

Converting to a RRIF at Retirement

Canadians must convert their RRSP to a Registered Retirement Income Fund (RRIF) by the end of the year they turn 71, at which point minimum withdrawals are required annually. For US tax purposes, a RRIF is treated the same as an RRSP under the Article XVIII treaty election — the same annual treaty statement applies. RRIF minimum withdrawals are reported as ordinary income on your US return, with credit for the Canadian withholding tax.

If you already retired to Canada or plan to and your RRSP has grown substantially, converting strategically and understanding the interplay with US Social Security income matters. The expat retirement account guide covers how US retirement accounts interact with foreign pension systems for context on the parallel issues.

Steps to Get and Stay Compliant

If you are behind on RRSP/TFSA reporting — whether missing treaty elections, FBAR filings, or Form 3520s — the path forward depends on how far back the gap goes and how large the accounts are:

1. Identify every registered account you hold. Run through your statement history for RRSP, TFSA, RRIF, LIRA (Locked-In Retirement Account), RESP, and any employer pension. Each may have its own reporting requirement.
2. Calculate historical FBAR and Form 8938 thresholds. If aggregate foreign accounts exceeded $10,000 in any past year, FBAR was due. Pull the maximum balance for each year from account statements before filing amended FBARs.
3. Attach RRSP treaty elections going forward. For each open year from now on, attach the Article XVIII statement to your 1040. For past years where the election was missed, consult whether an amended return or the Streamlined Procedures is the cleaner path.
4. Determine your TFSA filing position. If you take the position that TFSA is a foreign trust, prepare Form 3520 (and substitute Form 3520-A) for each open year. If the account balance is small and the years are few, the penalty exposure may be manageable. Engage a US-Canada cross-border tax specialist before deciding.
5. Consider closing or minimizing TFSA balances. If you plan to remain in Canada long-term as a US person, some advisors recommend keeping TFSAs at the minimum necessary for immediate needs and using RRSP and non-registered accounts instead, where the US treatment is clearer.
6. Hire a cross-border tax professional. The intersection of Canadian and US tax law is one of the more technically demanding areas in international tax. Standard US expat tax preparers often lack deep Canada-specific knowledge; a firm with dedicated Canada-US cross-border practice is worth finding. Charles Schwab's international program can help with the US brokerage side — it keeps US investment accounts accessible for Americans in Canada without triggering the account closure wave affecting other brokerages.

Annual Compliance Checklist for Americans in Canada

1. Collect December 31 and maximum balance statements for all registered accounts
2. Determine if aggregate maximum balance exceeded $10,000 USD equivalent — if yes, file FBAR by April 15 (or October 15 with extension)
3. Determine if balances exceed Form 8938 threshold — if yes, attach to 1040
4. Attach written RRSP/RRIF treaty election statement to Form 1040 or amendment
5. Report RRSP/RRIF income earned inside the plan on the treaty statement (not on Schedule B)
6. File Form 3520 for any TFSA held, unless you have a defensible position that it is not a foreign trust (document that position in writing)
7. Report TFSA investment income annually on Schedule B as ordinary income if not treating as a trust
8. Report RESP government grants as ordinary income in the year received
9. Review whether any RRSP withdrawal triggered Canadian withholding — claim the credit on Form 1116

Data note: Filing thresholds and treaty provisions were checked against IRS.gov and the US-Canada Income Tax Treaty in June 2026. The IRS has not issued definitive guidance classifying TFSAs as foreign trusts; the analysis in this article reflects the position taken by most US cross-border tax professionals as of 2026, but the legal position remains unsettled. Consult a qualified professional before making filing decisions.

Next Steps

The RRSP and TFSA are well-designed savings vehicles for Canadians — but they were designed without US tax law in mind, because most Canadians are not US persons. Americans in Canada are caught in the gap between two tax systems that don't talk to each other. The treaty solves the RRSP problem well. The TFSA problem remains unsolved at the policy level, which means individual Americans must navigate it themselves.

The highest-risk position is to ignore these accounts on your US return entirely. The lowest-risk position is to report everything and engage a professional who understands both systems. The cost of proper annual filing is much lower than the cost of a multi-year compliance catch-up after an IRS notice arrives.
